DESI constraints on two-field quintessence with exponential potentials
George Alestas, Marienza Caldarola, Indira Ocampo +2
The paper examines a dark‑energy model with two scalar fields having double‑exponential potentials that together behave like a single shallow potential, and tests its viability usi…
Realizing the phantom-divide crossing with vector and scalar fields
Shinji Tsujikawa
In generalized Proca theories, characterized by a vector field with broken gauge invariance, late-time cosmic acceleration can be realized with a dark energy equation of sta…
Crossing the phantom divide in scalar-tensor and vector-tensor theories
Shinji Tsujikawa
DESI observations of baryon acoustic oscillations (BAOs), combined with cosmic microwave background (CMB) and type-Ia supernova (SN Ia) data, suggest that the dark energy equation…
Tidal Love Numbers of Neutron Stars in Horndeski Theories
Robin Fynn Diedrichs, Shinji Tsujikawa, Kent Yagi
Precision measurements of the gravitational wave signal from compact binary inspirals allow us to constrain the internal structure of those objects via physical parameters such as…
